Custom Post Types in WordPress

You can also disable Gutenberg for a specific custom post
type by passing a callback function to the filter:

function wiverb_disable_gutenberg($is_enabled, $post_type) {
if ($post_type === 'wiverb_bike') {
return false;
}
return $is_enabled;
}
add_filter('gutenberg_can_edit_post_type',
'wiverb_disable_gutenberg', 10 , 2 );

What About Custom Fields?

Adding custom fields is a powerful way to add functionality

and structure to your custom post type data. If you are using

the Advanced Custom Fields (ACF) plugin, you can specify

that your custom field groups will appear on your custom

post type. You can then use data entered in these fields for

custom post type queries and templating.
